FIRE-HOSE NOZ ZLE Specification of Letters Patent.

Patented .Tune 15, 1909.

To all whom it may concern:

.Be it known that we, JOHN B. lINFIELD and CHARLES F. ACKERMAN, citizensof the United States, residing at Mansiield, in the county of Richlandand State of Ohio, have invented certain new and useful Improvements inFire-Hose Nozzles; and we do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in lire hose nozzles, andcomprises means for manually controlling a fire hose nozzle, and meansfor spraying water Ain front of the firemen.

One of the objects of the invention is the production of a lire hosenozzle provided with manually-operated means 'for spraying a stream ofwater so that a fireman may be able to clear the atmosphere of abuilding from smoke so that he may penetrate to the heart of a fire,and, at the same time, protect himself from the intense heat of a lirewhen working at close quarters with said fire.

Another obj ect of the invention is the production of a fire hose nozzlelcomprising a main discharge port and an auxiliary spray port, and meansfor separably and jointly opening and closing said ports.

W ith these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be described and particularly pointed out in the appended claim,and in the drawings, in which Figure 1 is a plan view of our improvedfire nozzle; FiO'. 2 is a side elevation; Fig. 3 is a centrallongitudinal sectional view taken in the line 3 3 of Fig. 1, showing theoperating valve in a closed position 5 Fig. l is a longitu* dinalsectional view taken on the line 4 4 of Fig. 1, showing the maindischarge nozzle opened by the operating valve; Fig. 5 is a longitudinalsectional view taken on the line 5 5 of Fig. 1, showing the spray portopened by the operating valve; Fig. 6 is a longitudinal sectional viewshowing the main discharge port and the spray port opened by theoperating valve; Fig. 7 is a horizontal sectional view taken on the line7 7 of Fig. 6 on an enlarged scale; Fig. S is a detail verticalsectional view taken on the line 8 8 of Fig. 1 Fig. 9 is a detailperspective view of the operating plug or valve; and Fig. 10 is a sprayport, 4.

similar view of the opposite side of' plug or valve.

In the accompanying drawings we have illustrated the preferredembodiment of our improved fire hose nozzle, which drawings are preparedsimply for illustrative purposes and therefore are not drawn to scale.

1 denotes a casing formed with a waterreceiving port, 2, a maindischarge port, 3, and a spray port, 4. The main discharge port, 3, andthe spray port, Ll, are positioned on opposite sides of the casing, 1,and said spray port is of considerably less area than the main dischargeport. The casing 1 is provided with an operating valve or plug, 5, whichplug is provided with a lever, 5, which is preferably formed integralwith said plug. The plug, 5, tapers inwardly from the lever 6 and isprovided with a squared portion, 7, and a threaded portion, 8. The plug5 is disposed in a lateral opening, 9, formed in the casing, 1, and issecured in place by a second lever 10, which is mounted on the squaredportion 7 of the plug, 5, and held thereon by a clamping nut, 11. Theplug, 5, is provided with a plurality of large openings, 12, 13, whichcommunicate with smaller openings, 11i, 15, 16 and 17. The openings, 12and 13, are arranged in the plug to allow water to pass from theconnecting hose to the main and auxiliary spray ports, and the smalleropenings are arranged to ]ointly connect the main and auxiliary sprayports and to independently connect the main and the auxiliary sprayports with the supply stream passing through the openings, 12 and 13.The levers, 6 and 10, are connected by means of a handle rod, 18, whichis provided with a hollow rubber or wood handle, 19, said rod 13 beingconnected at its ends by means of nuts, 20 and 2]., to the levers, 6 and10.

vWhen the main discharge port and the auxiliary spray port are closed,the operating valve or plug occupies the position indicated iny Fig. 6,and in this position the opening, 12, in said plug will be in alinementwith the water-receiving port, 2. Vv'hen it is desired to open theauxiliary spray port, the levers 6 and 10 are moved to the positionshown in Fig. 5, and when in this position water will ilow through theopening, 12, of said plug to opening, 15, and be discharged through theConnection between the spray port and the port 2 may be closed byturning the levers, 6 and 10 to the position shown in Fig. 6, whenconnection will be established between the opening 12 and the opening,17 By turning the operating levers to the position shown in Fig. 7, themain discharge port, 3, and the auxiliary discharge port, 4, will beopened simultaneously.

The main discharge port, 3, connects with a removable nozzle, 22, andthe auxiliary spray port, 4, connects with a removable spray nozzle, 23,which is provided with a re movable spirally-i'ormed core, 24. The waterpassing through the spray port, 4, will be given a s iral motion by thespiral core, 24, and spira ly move through the air after leaving thesaid nozzle.

A tail-piece, 25, is threaded to the hose receiving section of thecasing, l, and is provided with an enlarged ortion, 26, which is adaptedto hold a swivel? 27 against the end ofthe casing, l. The tail-piece,25, is preferably formed with integral lugs, 2S, and the swivel, 27, isprovided with external lugs, 29. The swivel, 27, is formed with internalscrew threads, 30, which are adapted to receive the threaded end of ahose section.

A swivel member comprising semi-circular sections, 31 and 32, is securedaround the casing, l. Each of said sections is formed with lateralprojections, 33 and 34, which are adapted to receive the ends of handstraps, 35 and 36.

By means of our improved ire hose nozzle a ireman or remen are enabledto project an auxiliary spray a considerable distance ahead of them, thedistance depending, of course, on the thickness of the stream and itspressure, and are enabled to instantly o en and close said auxiliaryspray, to immedlately open and close the main discharge stream, and toinstantly open and close the main discharge stream and the auxiliaryspray stream. By means of the spiral core, 24, the spray water is madeto cover a wide area.

From the foregoing description, taken in connection with theaccompanying drawing, the construction and operation of the inventionwill be readily understood without requiring a more extended exlanation.V

Variousy changes in the orm, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claim.

Having thus described our invention., what we claim as new and desire tosecure by Letters-Patent, is:

A device of the class described, comprising a pair of laterally spacedparallel nozzles, a body removably secured to said nozzles and having apair of divergng outlet ports leading from an inlet port, and a valveplug arranged between the outlet and inlet ports adapted toalternatively or simultaneously connect the outlet port with the inletport, and a solid core spiral secured slidably and removably in one ofsaid nozzles so as to give the water passing therethrough a rotary orspraying motion.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
